A safety broach for use in arthroplasty for hip joints, and a system including the same. The system may further include a segmented or otherwise flexible reamer and an implant. The safety broach includes a hollow interior passage that serves to guide the reamer when the safety broach is in place in the bone. The system may include any number of sizes of safety broaches, segmented reamers, and implants. In any case, such a safety broach may be capable of assisting with arthroplasty for hip joints (or any other joint), while typically providing enhanced safety and reliability of the arthroplasty.

The present application relates to a method for planning placement of an acetabular shell in a total hip arthroplasty (THA) procedure. Functional alignment of a 3D image of a pelvis includes identifying reference points on each 2D image of a weight-bearing pelvis, identifying corresponding reference points on a 3D image of the pelvis in a non-weight-bearing position, constructing a reference on the 2D images based on the reference points on each respective 2D image, constructing a corresponding reference on the 3D image based on the reference points on the 3D image, and aligning the corresponding reference of the 3D image with the references of the 2D images to provide a functionally aligned 3D image to more accurately plan placement of the acetabular shell.

The application provides a kind of based on deep learning's calculation method and system of postoperative eccentricity of total hip arthroplasty, it is related to medical technical field, can realize the accurate evaluation of the postoperative condition of the patient of total hip arthroplasty surgery, method includes: obtaining the hip image of the patient after hip arthroplasty surgery;Key point position and target area in the hip image are identified based on the target recognition network of deep learning;According to the key point position and the target area, the eccentricity of the patient is determined.The system executes the method.The application is based on the hip image of the patient after hip arthroplasty surgery, calculates the eccentricity of the patient after hip arthroplasty surgery, to realize the accurate evaluation of the recovery condition of the patient after hip arthroplasty surgery.

Provided herein is a computer-implemented method including obtaining values for non-modifiable risk factors, each defining an immutable patient characteristic determined to impact a likelihood that a complication results from an arthroplasty procedure. The system obtains first candidate values for modifiable risk factors of the patient defining a mutable characteristic of the patient or the arthroplasty procedure. The first candidate values are determined to minimize the likelihood that the complication results from the arthroplasty procedure. The system obtains second candidate values for the modifiable risk factors of the patient determined to maximize the likelihood that the complication results from the arthroplasty procedure. The system determines a personalized risk interval that represents a range of modifiable risk for the patient with respect to the arthroplasty procedure including determining (i) a lower bound and (ii) an upper bound for the personalized risk interval; and providing an output indicative of the risk interval.

The invention relates to the technical field of image processing, in particular to a total hip replacement dislocation evaluation system based on image processing, realizes full-process automatic analysis from image acquisition to risk visualization, and has the main advantages that the recognition precision of an anatomical structure is remarkably improved by an intelligent segmentation and three-dimensional reconstruction technology based on deep learning; manual errors are reduced; in combination with biomechanical analysis of habitual actions and static prosthesis matching parameters, risk quantification of dynamic and static combination is realized; a high-risk area is positioned objectively through weighted fusion of multi-dimensional parameters and threshold comparison.
